has_and_belongs_to_many关系的Rails路由 [英] Rails routing for has_and_belongs_to_many relationship

问题描述

我正在为运动队开发Rails 4 API，那里有很多球员和球队，但是我在Rails路由和has_many关系方面有些挣扎.我的球员和球队之间的关系如下:

I'm working on a rails 4 API for a sports team where I have players and teams and I'm struggling a little with rails routing and a has_many relationship. My relationship between players and teams looks like:

class Team < ActiveRecord::Base
  extend Searchable
  validates :title, presence: true
  has_and_belongs_to_many :players
end

class Player < ActiveRecord::Base
  extend Searchable
  validates :first_name, presence: true
  validates :last_name, presence: true
  has_and_belongs_to_many :teams
end

我希望能够将一个现有的球员添加到一个团队中，但是我不确定如何更改我的routes.rb文件.当前，它看起来像:

I'd like to be able to add an existing player to a team, but I'm unsure of how to change my routes.rb file. Currently, it looks like:

Rails.application.routes.draw do
  devise_for :users
  namespace :api, defaults: { format: :json },
            constraints: { subdomain: 'api' }, path: '/'  do
    scope module: :v1 do
      resources :users, :only               => [:show, :create, :update, :destroy]
      resources :teams, :only               => [:show, :create, :update, :destroy, :index]
      resources :players, :only             => [:show, :create, :update, :destroy, :index]
      resources :sessions, :only            => [:create, :destroy]
    end
  end
end

允许对玩家和团队模型进行CRUD操作.我当时想，要在现有团队中增加一名球员，我的路线将需要像这样:

which allows for CRUD operations on players and teams models. I was thinking that for adding a player to an existing team, my route would need to look like:

/teams/:team_id/add_player/

但是我不确定如何在routes.rb中声明该路由.因此，有几个问题:

but I'm unsure of how to declare that route in routes.rb. So, a couple of questions:

1. 从REST风格的角度来看，这种路线对人们有意义吗?如果是这样，我将如何在routes.rb
中声明这条路线
2. 将队员添加到团队中应该是PATCH还是POST方法?

1. Does that route make sense to people from a REST-ful perspective? If so, how would I declare this route in routes.rb
2. Should it be a PATCH or a POST method for adding a player to a team?

感谢您提供的任何帮助，

Thanks for any help offered,

推荐答案

您可以这样声明此路由:

You can declare this route like this:

resources :teams, only: [:show, :create, :update, :destroy, :index] do
  put 'add_player', on: :member
end

它将路线映射到TeamsController中的add_player操作.

It will map the route to the add_player action in your TeamsController.

从REST风格的角度来看，我还是建议您在players#update动作中进行此操作，因为您基本上是在更改玩家记录.

From the REST-ful perspective i would suggest you to make this in the players#update action though, since you are basically changing the player record.
